Answer:

Tension: No, Force of Gravity and Air Resistance: Yes.

Explanation:

The air resistance and the correspondent component of the force of gravity will do work since both they are parallel/antiparallel to the direction of motion. Tension will not do work, since its perpendicular to the direction of motion.
